      Estimation of grapevine vigour using mobile proximal sensors can provide an indirect method for determining grape yield and quality. Of the various indexes related to the characteristics of grapevine foliage, the leaf ...
    • LIDAR as an alternative to passive collectors to measure pesticide spray drift 

      Gregorio, Eduard; Rosell-Polo, Joan R.; Sanz Cortiella, Ricardo; Rocadenbosch Burillo, Francisco; Solanelles, Francesc; Garcerá, Cruz; Chueca, Patricia; Arnó, Jaume; Del Moral, Ignacio; Masip, Joan; Camp, Ferran; Viana, Rafarl; Escolà, Alexandre; Gràcia, Felip; Planas, Santiago; Moltó, Enrique (2014-01)
